Recharge after discharging the battery the first three times until it is fully charged. Then you can charge normally.
The correct way to use lithium batteries 1. Lithium-ion batteries have a lifespan. When you want to buy a battery, remember to look at the production date of the lithium-ion battery. Of course, the newer the better. Because your lithium-ion battery starts to “die” as soon as it leaves the factory. The lifespan of a lithium-ion battery depends on many factors. In a best-case scenario, your lithium-ion battery will lose 20% of its maximum charge capacity within a year of leaving the factory.
Proper use of lithium batteries 2. Do not let your device discharge.
Remember that a “one” charge cycle means that if you use 50% of the battery the first day, charge it overnight and use it again at 50% the next day . Theset a cycle.
Charging a lithium-ion battery repeatedly without interruption will not reduce battery life.
The correct way to use lithium batteries 3. Lithium-ion batteries will not be overcharged when charging. They have internal circuit protection. The biggest fear of lithium-ion batteries is the problem of excessive temperature, overshooting. The 40 degree temperature reduces the amount of energy a lithium-ion battery can hold.
Note 1. Storage of lithium-ion batteries
Lithium-ion batteries can be stored at an ambient temperature of -5°C to 35°C and at a relative temperature humidity not exceeding 75% clean, dry and ventilated room, avoid contact with corrosive substances and stay away from fire and heat sources. The battery power remains between 30 and 50% of the nominal capacity. It is recommended to recharge the batries stored every 6 months.
Note 2. Charging lithium-ion batteries
To charge lithium-ion batteries, a dedicated lithium-ion battery charger must be used.
Lithium ion battery charging adopts CC/CV (constant current + constant voltage) method, which means it is first charged with constant current and then switches to charging at constant voltage when the voltage reaches 4.2. V*n. Charging stops when the current decreases to 0.01C.
Note 3: Storing lithium-ion batteries once they are fully charged can reduce capacity loss.
This idea is completely false. Lithium-ion batteries are different from nickel-chromium and nickel- batteries. metal hydride batteries, because they have a very poor "aging" characteristic, that is, after being stored for a while, even if not recycled, some of theircapacity will be permanently lost. The reason is that the positive. and the negative electrode materials of the battery have been degraded since the beginning of its depletion process. The rate of “aging” is also different at different temperatures and power states.
Storage temperature and power status
Storage after 40% saturation and storage after 100% saturation
98% left at 0 oC (one year later) remaining 94% (one year later) Later)
25°C will leave 96% (one year later) will leave 80% (one year later)
40°C will leave 85% (one year later) will leave 65% (one year later)
60oC leaves 75% (one year later) and 60% remains (3 months later)
